PURPOSE:To enable to array plural light-emitting display devices in close contact to one another by a method wherein the first external lead-out electrodes and the second external lead-out electrodes are respectively formed in arrangement along the mutually opposing sides of the substrate using the lower electrodes and the electrode lead-out layers. CONSTITUTION:N<+> type layers 30, N type layers 21 and P type layers 20 are made to respectively grow continuously on a semiinsulating substrate 1. Lightemitting elements 10 and an electrode lead-out layer 60 in each line are separated from each other by performing a mesa etching. This mesa etching is performed up to reach the surface of the semiinsulating subtrate 1. The light-emitting elements 10 in each row are separated from one another by performing a mesa etching. This mesa etching is performed up to reach the lower electrode 30 of each row. Nitriding films 40 are formed on parts of the substrate 1, whereon an etching was performed. The contact holes of each of the light- emitting elements 10, each of the electrode lead-out layers 60 and each of external lead- out electrodes 31 and 61 are formed. After Al or Au was deposited on the surface, a photo etching is performed to form upper electrodes 50 and the external lead-out electrodes 31 and 61. As the first and second external lead-out electrodes are disposed along the mutually opposing end sides of the substrate 1 in such a way, plural light- emitting device can be mounted in close contact to one another. |
